Sudden drop in impressions on Google

Hi SEO, I have a hobby site that I built last September and it's done fairly well given no $ in ads/marketing. My "Dream interpreter" feature (a feature that allows you to explain your dream and it will interpret it using AI) is still getting 50-60 unique uses every 24 hours. I have not deployed any changes to the site in over 2 months, so nothing has changed on my end. I am unable to explain the sudden drop of impressions on google (using Google search console). My sitemaps are being read and updated daily with no issues; Google search console is not complaining about anything; HTTPS is active etc etc... Worth noting that previously (about 2-3 months ago), queries like "French fries dream meanings" used to show my pages in the first or second position, now i am struggling to see any results from my site altogether... Thank you (my previous post was banned because of a link containing images/screenshots - will retry and put the images in a comment)
